New, unsewn Nishijin-ori fukuro obi (formal obi). The "Toryumon" (Dragon Gate) refers to the Ryumon (Dragon Gate) mountain located upstream of the Yellow River in China. It's a rapid created by cutting through the mountain. According to an ancient legend, carp that successfully ascended the Dragon Gate would transform into dragons. This is the origin of the phrase "Toryumon," which symbolizes overcoming obstacles and achieving success in life. In Japan, the custom of raising carp streamers during the Tango no Sekku (Boys' Day) in May is derived from this story, expressing wishes for the healthy growth and success of boys. Carp are considered auspicious symbols of success because they climb waterfalls. This obi will be delivered after being sewn with a cotton core (Kanto style). It will take approximately 24 days to complete the sewing.
